I really like the ring a lot. It's very light, which means I can wear it while sleeping. The app provides access to all the info the ring collects. I also dance 2 or 3 times a week, and this light ring is much better for dancing than a large watch on my wrist. I took a star away only because of the appearance of the ring: to me, it looks like a ring a little kid would get out of a machine at a grocery store. Perhaps I should have gotten the black instead of the gold. Otherwise, it is a great product.
A tiny bit snug compared to the sizing kit. Incredibly impressive technology. A pedometer/heart monitor that lasts a week on a single charge is what most people have wanted out of their watch.
Finally, I got it yesterday on time as promised. As soon as I opened the box, I fell in love with it. Very satisfied so far. Too many features and information so I need more time to digest all, but I found the data are much more accurate than I expected after I got up and the checked my sleep score.
I pre-order since it went live. Just arrived have been wearing the sizing kit, size 11. Very light and confortable. Very happy with it. I used to wear the WHOOP 4.0, still was uncomfortable to sleep with at night. NOT any more! Overall very satisfied specially witn no Subscription is a huge plus!
